.This invention relates to an 'improved washing machine, and -onefoftherobjec'ts fof provide a device l'of this kind iinvwhichsimp'le,improved, eficient, and practical features of construction farefinvolved. l

One of the features-of=construction is to provide a washing machinereceptacle having 4va multiplicity Aof rolls arranged therein verticallyand consecutively annularly'ad'jacent the inner wall of the receptacle,and designed to rotate simultaneously, each in the same direction, andone toward the other, and provided with spiral grooves, the tendency ofwhich being to remove the dirt from the clothes as the rollers rub theclothes, and churn and agitate the suds toward the clothes.

A further feature of the construction is to provide the upper ends ofthe rolls with gears, there being a ring rack in mesh with said gears,to impart motion to the rolls.

A further feature of construction is the provision of a gear forimparting motion to the ring rack, and having means to hold the rack inposition on the upper end of the washing machine receptacle.

In practical fields, the details of construction may necessitatealterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings, and claimed.

In the drawings Y Figure 1 is a view in side elevation of the improvedwashing machine constructed in accordance with the invention.

Fig. 2 is a vertical sectional View of the machine, on line 2-2 of Fig.1.

VReferringtimore especially to the drawings, i1 adesi'gnat'es a "washingmachine recepftacle, Jwlhich may gbeof any Lsuitable shape orconfiguration, preferably cylindrical, and 'may lbe 'mounted upon afn-ysuitable E`leg ;s"2. (fh'ebottomi) oflthelreceptacle on lvits interioris provided "with plurality 'of sockets 21,to f'r'eceive andfconst'itute' -b 'arings `for the fpintles 5 of the vertical rolls 6,whichare a'rranged annularly adjacent fthe cylindrical wall l'ofthereceptacle l.

7j, 1in bearings "of Lwhich the pintles 5'8 of the rolls are mounted.The intles 8 areprovided with 'gears 9. A llo'sure "10 engages'the'opening l1 of the upper end of said receptacle. The exterior of thereceptacle 1 near its upper end is provided with a plurality of brackets12. A circular ring 13 angular in cross section fits upon the upper endof the receptacle 1. The inner edge of the iiange 14 of said ring hasgear teeth 15 meshing with the teeth of the gears 9, so that when thering 13 is rotated in one direction or the other, the gears 9correspondingly rotate, which in turn will rotate the rolls. The rollsrespectively rotate in the same direction one toward the other,

ed from being drawn in between the rolls. The rolls are provided withspiral grooves 16, and the grooves of every other roll eX- tend spirallyin an opposite direction to the grooves of the intermediate rolls. Thering 13 is angular in order to tit and rotate on the receptacle, asshown in Fig. 2. The exterior of the ring is provided with gear teeth17, which are engaged by the teeth 18 of the gear 19. A bracket 20 issecured by screws 21 to the receptacle 1, and is provided with acylindrical bearing 22, rin which the shaft 23 is mounted. Collars 24are se'- cured on the shaft 23 by the pins 25, one above and one belowthe bearing 22, to prevent axial movement of the' shaft shaft 23 has itsupper portion rectangular, so that the gear 19 will rotate therewith. Apulley 26 is fitted upon the rectangular portion 27 of said shaft 23, sothat any suitable power may be belted to the shaft, to rotate the v*gear19. The gear 19 has an annular Theiupp'er end 'of the receptaclehasanlinturnedannularflange n and byY so rotating the rolls the clothesare prevent- 23. The' extension flange 28, to overlie the ring 13,thereby preventing upward movement of the ring. rIhe brackets 12 overliethe ring 13, to insure holding the same in place. A suitable crank 29 isprovided, and has a socket 30, to receive the upper end of therectangularportion 27 of the shaft 23, whereby the shaft may be rotatedmanually, for operating the ring, which in turn will impart movement tothe rolls.

The invention having been set forth, what is claimed as new and useful,is

1. ln awashing machine of the kind set forth, the combination of acylindrical receptacle and a plurality of rolls having 0pposite spiralgrooves and mounted vertically in bearings of the bottom of thereceptacle to rotate adjacent to the interior wail of the receptacle, ofgears upon the upper ends of the rolls, and means mounted on thereceptacle meshing with the gears respectively to impart movement to therolls, all in the same direction.

2. In a washing machine of the kind set forth, the combination of acylindrical receptacle and a plurality of rolls having 0pposite spiralgrooves and mounted vertically Copies of this patent may be obtained forin bearings of the bottom of the receptacle to rotate adjacent to theinterior wall of the receptacle, of gears upon the upper ends of therolls, and meansmonnted on the recep tacle meshing with the gearsrespectively to impart movement to the rolls all in the same direction,said means comprising a circular ring angular inicross section to fitthe upper end of the receptacle, brackets to support said ring and holdthe same in place, one flange of the ring having teeth on its inner edgemeshing with the gears respectively of the rolls, said ring havingexterior teeth, a shaft mounted in a bearing on the exterior of thereceptacle, and a gear mounted on said shaft to rotate therewith andmeshing with the exterior teeth of the ring and having an annularextension iiange overlying the ring to prevent raising of the ring, andmeans for rotating said shaft.

In testimony whereof l have signed my name to this specification in thepresence of two subscribing witnesses.
